Well, Error response without headers was observed in www.mozilla.org and www.google.com for Invalid requests. But, I observed something surprising at www.apache.org If you do GET / HTTP/1.0 You do get the valid Response with headers. But if you do GET / You get a valid response Without headers. I was afraid if this behavior was to support HTTP 0.9 style where the the reponse is sent without the headers. Actually, it is turning out to be true: http://ftp.ics.uci.edu/pub/ietf/http/rfc1945.html#Response According to HTTP 1.0, When a request is Simple-Request, it means a VERB URL (without a version) and it generally corresponds to HTTP 0.9 And when a server receives such a Simple-Request, it sends a Simple-Response where it does not send the headers back. I think, the same is exhibited by other Servers as well www.google.com, www.mozilla.org where for Invalid Request without version, you are sending a Simple-Request (HTTP 0.9) style and getting the corresponding response. Given these, any assumption that servers no longer support HTTP/0.9 becomes false. So nuking it will require some thought. -- Senthil -- _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
